With all the heat records destroyed this year, Mother Nature turned her eraser to modifying some rain records too this autumn... and giving skiers a bit of an "I'm sorry" present for ruining last year's season.

Fresh off the worst ski season BY FAR last year, thanks to "The Blob" of warm waters in the Pacific, skiers have been treated to a record early season snowfall.

Snoqualmie Pass has tallied 193.3 inches of snow in December, making it their snowiest December on record, breaking the old record of 192 inches set in 1968.

Overall, Snoqualmie Pass sits at 208 inches of total snow for the year, which doubles last year's entire season of 104 inches.

Amidst the barrage of snowstorms, the pass also set its record for heaviest 7 day snowfall total, reaching 112 inches (just over 9 feet!) between Dec. 18-24. Previous record for week-long snow dump was 102 inches set between Jan. 27 and Feb. 2 in 1990. And yes, that means Snoqualmie Pass got more snow in a week this year than they did all of last year.

All the snow up there fell as a whole bunch of rain in the Puget Sound region. While none of the 208 inches of snow fell as accumulating snow in Seattle, we did manage what will go down as the top 3 wettest autumns on record at Sea-Tac Airport.

December is finishing up with 11.21 inches of rain -- the second wettest December on record for Sea-Tac, missing the record of 11.85" set in 1979.

It's also the 6th wettest month on record overall at Sea-Tac Airport:

  1. 15.63" Nov 2006
  2. 12.92" Jan 1953
  3. 11.85" Dec 1979
  4. 11.65" Jan 2006
  5. 11.62" Nov 1998
  6. 11.21" Dec 2015
  7. 10.71" Nov 1990

** 15.33" fell in December 1933 in the Downtown Federal Building.

What about combining with our soggy October and November? It's the third wettest both Oct-Dec and Nov-Dec. on record at Sea-Tac:

Oct-Dec:

  • 1) 25.06 (1955)
  • 2) 24.48 (2006)
  • 3) 24.39 (2015)

Nov-Dec:

  • 1) 22.93" (2006)
  • 2) 20.60" (1998)
  • 3) 19.58" (2015)

December had the soggy distinction of having it rain at some point on the first 28 days of the month. It's on the heels of 21 rainy days in November and 17 days with rain at some point in October -- meaning it rained at some point on 7 out of every 10 days this autumn.

But as the year ends, so does the rainy pattern. 2015 will end bone dry, and long range models suggest there will be little-to-no rain in the first two weeks of 2016. So skiers, get up there and enjoy the snow now!
